In Episode 3 of "How to Build a Steam Engine" With the boiler now complete, it's time for Alex and his team to begin constructing the wheels. These need to be designed, cast, and built from scratch, before being sent to a specialist facility to be rubbered. Building wheels to the scale, strength, and accuracy needed for an engine like 'Talisman' is no mean feat, and Alex Sharphouse and Guy Martin have certainly had their hands full on this job.
